is this a scientific model? use complete sentences to explain why or why not.

This would be consider a scientific model. A scientific model gives a visual representation of a scientific idea or process. A 2D scientific model is mainly Diagrams, sketches, or drawings wall a 3D model is some kind of object that you would be able to hold. For example this model is a 2D model, it is showing the vegetation in the world. Dark green has more vegetation was tan has less. This would be consider a scientific model because you can see whats happening threw a drawing.

I hope this help. If its wrong I will fix, but if its right please give brainiest! Thank you, have a good day!!!

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.
